I would like to route notifications of registrants to different emails based on a drop down. I know that notification routing is the way to do this. For the routing "send to" field, I've only seen examples of explicitly entering an email. But the email addresses I need to enter are tied to user admins on my site. If their user email address changes, then the routing email becomes obsolete since it's not tied to the user.
Could it be possible to tie the notification routing "send to" field to the email address of a user?
